This study intends to analyze the various spatial structures and characteristics of the museum based on the two of the Renzo Piano's recent projects Menil Collection '||'&'||' Museum and Beyeler Foundation Museum Which defined the direction of the "Third Generation" in museum architecture with reference to the quality of spatial experience and design applications. Comparison and analysis were done on the basic spatial organization floor layout accessibility exhibition area lighting plan and circulation between the two museum. Through the itemized common characteristics of the museum the architect's proposal on meaning and direction of the new museum architecture can be viewed. The contemporary museums distinguish themselves quite clearly from their predecessors and this applies both to their own form and to their spatial organization. As the public demands and requests toward the museum building facility expand everyday the architect must respond by providing multiple types of space where people can experience different atmosphere in each area. One concept he used to create multi experienced area was manipulation of the natural light using by the state-of-the-art techniques of the light filtering system and multi-layering roof system to protect the valuable collections against the direct sunlight. But mainly it was to prove his strong belief in "architecture of light" by creating space with minimized meaning by purposely distinguished area in order to provide maximum support to the physical value of the collection " The connection with nature" is another concept which Piano used to provide the public a tranquil experience through out the architecture which engages in a lively dialogue with art. In spatial organization Piano concerned on functionality which not only concentrated on the visitor's point of view but also on the museum staff's comfort. Unlkie the traditional museum he alternates various size of exhibition areas for spatial hierarchy. Specially the spatial flexibility that the temporary exhibition areas are able to be expanded to the permanent exhibition areas by adjoining t재 spaces differentiate Piano's new museum from the rest. museum from the rest.

This study is to present the design methods in the Schrider House executed by the Dutch architect G. Th, Rieveld. The plastic principles which underlies the architecture design are examined through the analysis of the 'new structural joint system (Cartesian Coordinate System) ' and ' Color-Plasticity ' which characterized a series of his furniture design from 1918 to 1924. It indicates that Reitveld attempted to realize the simplicity, clarity and flexibility of spatial expression in his first independent architecture by the application of technical skills which have been developed in his early days.

The paper describes a new approach to the organization of an artificial brain for mobile multi-robot systems, where individual robots are not considered as independent entities, but rather forming together a universal parallel and distributed machine capable of processing both information and physical matter in distributed worlds. This spatial machine, operating without any central control, is driven on top by distributed mission scenarios in WAVE-WP language. The scenarios can be written on a variety of levels, and any mixture of them, supporting the needed system flexibility and freedom ...

GIS 기술의 발달로 많은 양의 공간 데이터가 축적됨에 따라 공간 데이터 마이닝의 중요성이 커지고 있다. 본 논문에서는 새로운 공간 데이터 마이닝 시스템 SD-Miner를 제안한다. SD-Miner는 크게 입력과 출력을 담당하는 사용자 인터페이스, 공간 데이터 마이닝 기능을 처리하는 데이터 마이닝 모듈, DBMS를 이용하여 데이터를 저장하고 관리하는 데이터 저장 모듈의 세 부분으로 구성된다. 특히, 데이터 마이닝 함수 모듈에서는 공간 데이터 마이닝의 주요 기법인 공간 클러스터링, 공간 분류, 공간 특성화, 시공 간 연관규칙 탐사 기능을 제공한다. SD-Miner는 다음과 같은 특징을 가진다. SD-Miner는 사용자로 하여 금 공간 데이터 마이닝뿐만 아니라 비 공간 데이터에 대한 마이닝도 가능하게 하며, 각 마이닝 함수들을 라이브러리 형태로 제공하기 때문에 다른 시스템에서도 쉽게 사용 가능하다. 또한, 마이닝 매개 변수들을 테이블의 형태로 입력받기 때문에 시스템의 범용성이 높다. 개발된 SD-Miner의 실용성을 규명하기 위하여 실제 공간 데이터를 이용한 데이터 마이닝을 수행함으로써 여러 가지 의미있는 결과를 도출한다.

The purpose of this study was to investigate the possibility of applying the planning characteristics of Neowa houses to contemporary residential structures. Contrary to the popular assumption that traditional Korean houses have decentralized plans, local building traditions observed in Neowa houses show that the diversity among hanoks allows the incorporation of traditional spatial organization into the contemporary residences. By analyzing the spatial organization of Neowa houses, three advantageous planning characteristics were found. First, the presence of indoor wooden floors (maru or daechung) as well as outdoor wooden floors in Neowa houses is practical for Korea's weather marked by humid summers and icy winters. Secondly, the internal orientation of space in Neowa houses is more appropriate in the contemporary context of a highly urbanized society emphasizing family privacy. Thirdly, the flexibility and interchangeability of interior elements can be applied to improve efficiency. By applying the aforementioned characteristics, this study suggests ways to adopt traditional features to improve contemporary residences.

In today's pervasive computing environments, multimedia content should be adapted to meet various conditions of network connections, terminals, and user characteristics. Scalable Video Coding (SVC) is a key solution for video communication over heterogeneous networks, where user terminals have different capabilities. This paper presents a standard-compliant approach that adapts an SVC bitstream to support multiple users. The adaptation problem is formulated as an optimization problem, focusing on the tradeoff between qualities of different spatial layers of an SVC video. Then the adaptation process is represented by standard metadata of MPEG-21, which can be solved by universal processing to enable interoperable and automatic operation. Our approach provides the users with optimal quality, a wide flexibility, and seamless adaptation. To the best of our knowledge, this is the first study that shows the adaptation tradeoff between spatial layers of a conforming SVC bitstream.

생활 수준의 향상으로 환경의 질에 대한 주민들의 관심이 높아짐에 따라 쓰레기 매립지와 같은 환경 혐오시설의 부지 선정 문제가 사회 문제로 대두되고 있다. 따라서 본 연구에서는 다량의 환경학적 정보를 저장, 관리, 분석, 표시할 수 있는 GSIS와 의사 결정 과정에서 사용될 수 있는 AHP를 이용하여 쓰레기 매립지를 평가하는 방법을 연구하고자 한다. AHP는 관계 집단들의 의견을 적절히 반영시킬 수 있는 유연성을 가지고 있기 때문에 GSIS와 연관시켜 사용하면 환경 혐오시설의 부지 선정 문제에 매우 유용하리라 생각된다.

Frame is one of the most commonly used structural systems for the resistance of applied loads. Many researchers have recently conducted their studies to investigate the effect of several parameters such as the connection flexibility, boundary condition of each support, beam-to-column stiffness ratio. These parameters play important roles on the characteristic behavior of frames. A simplified spring model is proposed to obtain the story drifts of frames with various beam-to-column connection stiffnesses in this research. A point bracing system with adequate spring stiffness is also suggested to establish the relationship between the applied load and the resisting translational spring stiffness within the limit state of story drift.

This paper aims to advance our understanding of extensible beams with multiple cracks by presenting a crack energy and motion equation, and mathematically justifying the energy functions of axial and bending deformations caused by cracks. Utilizing an extended form of Hamilton's principle, we derive a normalized governing equation for the motion of the extensible beam, taking into account crack energy. To achieve a closed-form solution of the beam equation, we employ a simple approach that incorporates the crack's patching condition into the eigenvalue problem associated with the linear part of the governing equation. This methodology not only yields a valuable eigenmode function but also significantly enhances our understanding of the dynamics of cracked extensible beams. Furthermore, we derive a governing equation that is an ordinary differential equation concerning time, based on orthogonal eigenmodes. This research lays the foundation for further studies, including experimental validations, applications, and the study of damage estimation and detection in the presence of cracks.
